Influencing Voters When getting voters to support a candidate in an election, is there a difference between a recorded phone call from the candidate or a flyer about the candidate sent through the mail? A sample of 500 voters is randomly divided into two groups of 250 each, with one group getting the phone call and one group getting the flyer. The voters are then contacted to see if they plan to vote for the candidate in question. We wish to see if there is evidence that the proportions of support are different between the two methods of campaigning. (b) Possible sample results are shown in Table 4.3. Compute the two sample proportions: p^c, the proportion of voters getting the phone call who say they will vote for the candidate, and p^f, the proportion of voters getting the flyer who say they will vote for the candidate. Is there a difference in the sample proportions? Table4.3Sample A: Is a phone call or a flyer more effective?

Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.

Influencing Voters
When getting voters to support a candidate in an election, is there a difference between a recorded phone call from the candidate or a flyer about the candidate sent through the mail? A sample of 500 voters is randomly divided into two groups of 250 each, with one group getting the phone call and one group getting the flyer. The voters are then contacted to see if they plan to vote for the candidate in question. We wish to see if there is evidence that the proportions of support are different between the two methods of campaigning.
(b)
Possible sample results are shown in Table 4.3. Compute the two sample proportions: p^c, the proportion of voters getting the phone call who say they will vote for the candidate, and p^f, the proportion of voters getting the flyer who say they will vote for the candidate. Is there a difference in the sample proportions?
